9.













a. Atrial fibrillation
b. Atrial flutter
c. Junctional rhythm
d. Idioventricular rhythm


10.












a. Monomorphic ventricular tachycardia
b. Polymorphic ventricular tachycardia
c. Supraventricular tachycardia
d. Multifocal atrial tachycardia




Answers

01. c. Ventricular paced
02. c. 2nd degree block type II. In this strip there are some nonconducted P waves present. On the conducted beats the PR interval remains constant.
03. d. Complete heart block. No association betwen the P waves and the QRS complexes.
04. b. AV paced. Both the atria and the ventricles are being paced. So dual paced.
05. a. Atrial fibrillation
06. b. Atrial fibrillation with rapid ventricular rate
07. d. Ventricular fibrillation converting to atrial fibrillation.  Notice the very long QT interval of 0.56 sec on this patient. Although you would calculate the actual QTc interval based on the rate, any QT interval longer than 0.44 sec should be looked at with suspicion.
08. a. Normal sinus rhythm with a PVC
09. b. Atrial flutter
10. b. Torsades de pointes
